Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The ErbB3 protein also known as HER3 is a member of the epidermal growth factor receptor (EGFR) family. It belongs to the ErbB receptor tyrosine kinase family but lacks intrinsic kinase activity. The HER3 protein has a molecular weight of approximately 180 kDa. You will find HER3 expressed in various tissues with high expression in the epithelial tissues where it plays a role in normal cellular processes. HER3 interacts with multiple ligands facilitating cellular communication and growth regulation.
Biological function summary

HER3 is essential for activating important signaling pathways that regulate proliferation differentiation and survival. The ErbB3 protein forms heterodimers with other ErbB family members such as ErbB2 (HER2) which is necessary for its signaling capability. The HER3 protein is abundant in heart and nervous tissues indicating its role in cardiovascular and neurological functions. Its activation modulates gene expression through downstream effectors mediated by dimerization.

Pathways

HER3 plays a pivotal role in the PI3K/Akt and MAPK signaling pathways. These pathways are fundamental in cellular responses like growth and survival. HER3 serves as a major partner for HER2 in these signaling cascades enhancing downstream signaling effects. HER3's connection to these pathways makes it a critical node collaborating closely with proteins such as HER2 and EGFR to maintain efficient communication and function within these networks.

HER3 associates strongly with cancer and cardiovascular diseases. Its overexpression in certain cancers such as breast cancer leads to enhanced tumor growth and resistance to therapy. HER3’s relationship with the HER2 protein is especially significant in HER2-positive breast cancer where their interaction drives tumor progression. Additionally alterations in HER3 expression or function impact cardiovascular diseases as it plays a significant role in heart and vascular cell behavior. Recognizing HER3's involvement in these conditions allows for targeted therapeutic approaches and improves disease management strategies.

Target data

Tyrosine-protein kinase that plays an essential role as cell surface receptor for neuregulins. Binds to neuregulin-1 (NRG1) and is activated by it; ligand-binding increases phosphorylation on tyrosine residues and promotes its association with the p85 subunit of phosphatidylinositol 3-kinase (PubMed : 20682778). May also be activated by CSPG5 (PubMed : 15358134). Involved in the regulation of myeloid cell differentiation (PubMed : 27416908).
